Panasonic Lumix FZ1000 - Rattling sound

I would imagine it is the IOS moving.
It's the IS system either moving the lens assembly or, if IS is off, keeping it centered.
With the camera off and you move it around, you can hear the IS assembly "thump" inside. It happens with my Fuji macro lens, and is a fairly common thing.
If you google 'Lumix F1000 noise', there's a few forum threads out there on the subject...
